Yamaha introduced three new entry-level Waverunner models for 2010: the VX Sports, VX Deluxe and VX Cruiser. These new models are all loaded with great attributes and amenities, starting with improved comfort and stability, as well as excellent FZS-inspired styling.

Quiet and effective
Under the seat you will find the familiar 1,052-cc, DOHC, 5-valve per cylinder, 4-stroke, 4-cylinder MR-1 engine derived from the 2006 Yamaha R1 sportbike. Data on power and torque are not available. Capable and particularly fuel-efficient, this proven mill rates among the cleanest in the industry. Cooling water flow through the engine is managed by a thermostatic valve that sets the amount of water going to the water pump according to engine temperature, as does Kawasaki. As is the trend, zinc anodes protect the engine from harmful galvanic corrosion, while stainless steel fasteners (nuts, bolts, hardware) provide a long service life.

The 155-mm, axial-flow, single-stage turbine and the progressive pitch impeller provide optimum balance between takeoff and high speeds. Furthermore, accurate tolerances between the impeller and the housing, the dynamic shape of the front hull section, as well as the streamlined duct and grate, optimize thrust, performance and hook-up both on still and more agitated waters.

Electronics to the rescue
The Yamaha Engine Management System (YEMS) controls and adjusts basic functions such as Off-Throttle Steering, which keep the throttle slightly open at very low speeds to maintain the ability to steer the machine. A Slant Detection Switch stops the engine if the craft tilts excessively or rolls over, thus preventing water from entering the air intake duct.

In terms of noise, the VX engine remains quieter than the average thanks to Yamaha’s patented noise cancellation system, which uses hull-integrated mufflers to better dampen intake and exhaust noises.
